WILLIAM P. WENTWORTH, OF SENECA FALLS, NEW YORK.
IMPROVEMENT IN CLAMPING DEVICES FOR FILING SAWS.
Specification forming part of Letters Patent No. 214,071 dated April 8, 1879; application filed January 21, 1878.
To all whom it may concern:
Be it known that I, WILLIAM P. WENT- WORTH, of Seneca Falls, in the county of Seneca and State of New York, have invented a new and useful Improvement in a Clamping Device for Filing Saws, of which the followin g is a specification.
My invention relates to the manner of pivoting the jaws of the clamp together, also to the device employed to close and open the jaws of the clamp; and, further, to the providing a muffler of the sound produced by filing the saw.
Figure 1 is a perspective view of my invention. Fig. 2 is a plan view of the operating-lever. Fig. 3 is a detached view of one of the aws.
Arepresents the stationary jaw, which forms a part of the frame L,which frame is provided with suitable means for attachment to a workbench or other suitable support. Upon the outer edges of this frame are formed the two projections or standards as, between the upper ends of which is pivoted or journaled the lever E, which has the movable jaw B secured to its upper end. The pivots y, upon which the lever E turns, pass through the lever at that point where the outer surface is curved and rounded, so as to form as small a bearing-surface as possible. If so desired, this curved surface may be formed on the inside standards, w, or both the lever and the standards may be curved. The lower end of this lever is kept from any side movement by means of the pins or stops g, and the lever is caused to rock or move back and forth upon its journals or pivots by having its end bear against the lever G, which has the cam D formed upon it. As this lever is turned upon its pivot F, the end of the lever E is forced either in or out, as may be desired, and thus the jaw B is made to open or close at will.
Secured to the lower edge of the jaw B is a cushion of rubber, M, which is set in a recess formed along the lower edge of the jaw, so as to protect it, and which rubber forms a cushion, so as to deaden the noise of the saw while being filed.
The form of the cam D is best shown in Fig. 2, and projecting out over this cam is a horn or arm, 13, which catches over the outside of the lever and keeps it in contact with the lever 0.
Having thus described my invention, I claim- 1. The lever 0, having the cam D and arm '5, in combination with the lever E and stops g, substantially as set forth.
2. The jaw B, having the cushion M secured to its lower edge, substantially as specified.
WILLIAM P. WENTWORTH.
